Answer:

65 non-fiction books need to be shelved

Step-by-step explanation:

This question can be solved using a rule of three.

For each 5 non-fiction books, there are 9 fiction books. How many non-fiction books are there when there are 117 fiction books?

5 non-fiction - 9 fiction

x non-fiction - 117 fiction

$9x = 5*117$

$x = \frac{5*117}{9}$

$x = 65$

Kaylis [27]

Answer:

The blue liquid is toxic

Step-by-step explanation:

From the calculations I have done and attached to this problem

Null hypothesis:

H0 : p1 <= p2

Alternate hypothesis:

H1 : p1 > p2

^p1 = 0.925

^p2 = 0.2250

^P = (x1 + x2)/(n1+n2)

= 0.575

After calculating, I got test statistics = 6.33 ( check attachment)

P(z > 6.33) = 0.0000

In conclusion, our pvalue has been found to be less than the level of significance 0.05 so we reject null hypothesis and accept that we have enough sample evidence that the blue liquid is more toxic in comparison to white one.

Please check attachment for calculated test statistics.

Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the given equation.

Pani-rosa [81]

y = - 4x +3 when slope is -4

NOTE: Parallel lines have same slope.

For the line passing through point (-5, -6) the slope (m) = -4

Equation of that line:

(y - y1) = m (x -x1)

(y --6) = -4(x --5)

(y + 6) = -4(x + 5)

y + 6 = -4x -20

y = -4x -20 -6

y = -4x - 26

I need the answer or help to 6-23

Maurinko [17]

This is a system of equations.
Let L represent Lucia, and B represent Ben
The first equation is:
L + B = 150
The second one says that for every dollar ben saved, Lucia saved twice as much. So:
L = 2B
Now, solve the system
2B + B = 150
3B = 150
B = 50
L = 2(50)
L = 100
This means that Ben saved $50, and Lucia saved $100
